By unfolding into a cellular chain
, clusters of cancer cells can slide through capillary tubes less than 10 micrometers wide, Sam Au of Harvard Medical School and colleagues report in the May 3 Proceedings of the National Academy of Sciences.
In a kind of cellular chain
reaction, Chawla's team found that when eosinophils at the site of muscle injury secrete a molecule called IL-4, FAP cells respond by expanding their numbers.
If the cellular chain complexes of [SIGMA] and [PSI] are algebraically dual (for example, if [SIGMA] and [PSI] are Poincare dual cell structures on a compact orientable d-manifold), then [K.
2] of the real projective plane, whose cellular chain complex is
Let [SIGMA] be the cell complex whose cellular chain complex is
They can also start the cellular chain
reaction that leads to inflammation.
I must pick it up, where he threw it in the dirt, the pointless cellular chain
